Glock 44 22LR with the ProMag 18 round mag, Modifications I made to help with reliability. 

I jammed 20 and 21 rounds in mine and left it loaded for 3 weeks. I’ve bought 4 of them and all 4 run flawlessly now. 0 malfunctions through about 2000 rounds. Do that they’ll be good to go.

Just bought a Glock 44. Thanks for the mods.

Never had a pro mag that I would trust.

Thanks for the review. I'll stay away from ProMag.

Thanks, I have my mags coming in.

My g44 extended clip carry’s 25 rounds works flawless. I don’t think anyone has a chance 25 +1 rounds rapid fire on target ! No brainer! Great buy for sure!

I have 2 PMAG with my G44 and I did nothing as all is ok. But the critical point is : Use only speed cartridge specially if as me you are using a suppressor. So CCI stinger, Winchester X, all spedd egal or more than 400 m/s.

thanks for the promag tip...I didn't know they had a 18 rd mag. When I bought my glock 44 I bought 2 extra 10 rd mags. I wished I used that money to by a 18 rd mag.

listen ppl you cannot load a .22 mag for any .22 on the market and have it shoot reliably I have put 3,000 rounds through the 18rd promags they work just fine with shit ammo u just have to load them right the way this man loaded these mags or stock mags or mark mags they will not feed period.

I did the spring cut on 2 of my promag 18rounders like in your video, ran smooth as butter

Just watched your video and realized it was two years old but thought that you might try taking the spring out of a ten round mg and put it in the pro mag and see if the mag pro functions.

Same poor results in four 18rounder ProMags using Golden Bullets. Wouldn't load until I bent 6-7 rounds and the mag was loaded with 12 or less.

Had misfeed problems with the Remingtons on the factory glock mags... switched to cci mini-mags and all problems went away. It oddly enough was usually with the first round, but not always. Dont know why the cci works perfectly. Same for the M&P 22lr also, so its got to be the ammo.

Have you try them yet after cutting the spring

So what happened after actual live fire

Hello i enjoyed your video thank you. I just ordered a 18rd & 25 rd mag hope to have it in a couple days...looking forward to running these mags with my 22 Switchback Suppressor...also would like help with subscribers if you would be so kind...just starting off

Hi from france, i have the same problem!!! bought 3 and the 3 make the same thing like your video!!!! DONT BUY THEM!!!!!!!!!!!!!!

Didnt watch the vid, long story short, if i pay for it i expect it to work without any mods whatsoever, thats what i pay for so i expect the mamufacturer to do that

Worst glock ever made, oh you want a g19 trainer? Thats what it was designed for Well 15 rd mags dont exist, you want a threaded barrel and red dot? Well now you have over $1200 into a .22lr handgun and a 2 month wait for a red dot slide. Mags are very hard to load, and most times they jam like crazy and very picky on ammo, seriously just buy a tx22c and dont look back for $400 and has everything you could possibly want. Glock shit the bed on the 44 NOBODY asked for a plastic slide not one person you cant even really put better iron sights on it or suppressor height if you wanted without risking destroying the slide
